' To all whom z't may concern.

Be it known that I, MARKUS WALINT, a

subject of the Emperor of Alistria-Hungary,-

ing is a specification.

My invention relates to improvements in devices for making artificial 10c, and 1t conslsts 1n the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide means whereby a number of blocks of ice' may be, quickly and cheaply manufactured through the agency of a freezing compound.

A further object of my invention is to provide a machine or device for manufacturing ice which will accomplish the freezing of the water in a very short time.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings forming part of this application in which similar reference charac ters mdlcate like parts in the several vlews,"

and .in which- .Figure 1 is a vertical section through the device, Fig. 2. is a plan 'view of the device with the cover removed, Fig. 3 is a section along the line33 of Fig. 1, and Fig. tis a section along the line 44 of Fig. 1.

In carrying out my invention I provide a-rectangular casing 1 provided with a par tition 2 which divides the easing into two compartments 3 and 4 respectively. The compartment 3 is the ice making compartment, while the compartment 4 is designed to house the motor and fan.

The casing 1 is made of Wood or other similar nonconducting materials The compartment 3 is lined with tin or other suitable metal such as shown at 5, and the space between the metal lining 5- and the outer motor M and a fan the motor being con- ;nected with the fan so as to drive the latter. Within the compartment 3 is a coil of pipe ICE-MAKING .DEVIGE.

9 which lies above the floor of the compartment. This coilof pipe in fact, consists of two pipes, one within the other as shown in Fig. 4. The outer pipe 9 communicates with a water supply 10 while the inner pipe 9 communicates with the fan F. The opposite end of the pipe 9 has an outlet 11 while the pipe 9 is bent inwardly toward the center of the compartment and terminates in a tunnel or bell 9?. Disposed on the inner 'llnlng 5 near the top on each side of the compartment 3 is an elongated flange 12 as chown in Figs. 2 and 4.

Arranged to fit within the compartment 3 are a series of cans 13 and '14. These cans are provided with hooks 15 which arrange to engage the flange 12 so as to suspend the cans within the compartment. The cans 13 which alternate with the cans 14, are designed to receive a freezing mixture. This freezing mixture may be any suitable substance, but is preferably a mixture of ice,

salt and lye, the latter consisting almostentire'ly of potash. -The salt may be coarse salt and does not have-to be pure, since any volatile matter, which would tend to render -t-he air surrounding the cans impure, will be carried away in the manner hereinafter explained.

From. the foregoing description of the various parts of the device the operation thereof. may be readily understood. The stop cook 10 in the water inlet 10 is opened, the cock 11 of the outlet 11 also being opened. This permits water to flow into the pipe 9. As soon as the. pipe is filled the cocks 10 and 11 areclosed. The cans containing the freezing mixture are placed on their supports and those containing the wa ter to be frozen are placed between the cans containing the freezing mixture as de scribed. The cover 8 is closed and the fan is started by the motor. Air is drawn in through the opening 15 (see Fig. 3) into the compartment 4 and into the fan F, whence itis forced into the pipe 9 which is surrounded by water. Here the air is given a preliminary cooling. The air is delivered from the funnel 9 underneath the cans 13 and 14:. It will be noted that there is a space surrounding the cans by which the air can have access to all sides of the can. The fan rotates slowly and there is a slow current of air which passes up around the cans and is discharged through the opening 17 (see Fig. 1) into the outer compartment. An opening 18 is provided in the casing so as to permit the slow discharge of air. e 5 passage of the air through the pipe 9 causes the air to become chilled before being passed over the cans. The water remains chilled owing to its Proximity to the cans. It has been found that withaslight current 10 of air flowin around the cans the time of 1 freezing the ice is much less than where no.

suchcirculation takes place. Furthermore, the air is prevented from becoming foul by I L the steady, but small discharge through the sopening 18. When-the air is iven a reliminary chilling prior to its elivery into the space around the cans all of the cans -\containing the ice produce about the same product, but where the air is not chilled there. is a tendency for-*the can which is situated nearest the discharge pipe 'to take a longer time in freezing a block of ice. After the ice has been frozen the cans may be lifted out of the compartment and emptied of their contents. It is found in practice that one charge of freezing mixture is sufficient for three or four batches of ice.

) I- claim:

In a device for making artificial ice, a

casing divided into two compartments, a

fan in one compartment, a motor therefor, the other compartment being provided'with non-conducting walls, a coil of concentric pipes disposed near the bottom of the latter compartment, a connection between the fan and the inner of said pipes, the outer of lishing communication between said compartments, and an air passage leading from one of said compartments to the outer atmosphere:
